When all of thecorresponding angles are congruent, the picketsmust be parallel.41.The 10-yard lines will be parallel because theyare all perpendicular to the sideline and two ormore lines perpendicular to the same line areparallel.42.Consecutive angles are supplementary; oppositeangles are congruent; the sum of the measures ofthe angles is 360.
